duction of a novel, useful, and feasible arrangement and control of thevarious means employed.

In the drawing forming a part hereof Figure 1 is a representation indiagram of the mechanisms employed together with the circuits and therelation of the same.

Fig. 2 is a section on the line 2-2 of Fig. j

Fig. 3 is an end view of the switohbar A and a front view of carrier AFigs. 2 and 3 show the relation of the contact h of carrier A and itsadjacent projecting contact 7 of switchbar A t The re-' lation of theother carrier contacts to their respectively adjacent projectingswitchbar 1 contacts is similar to that shown in Figs. 2-

and 3. i

Fig. 4 is a side view of a key and its associated contacts. v I Fig. 5is a view in perspectiveof a por tion of a carrier, as A, viewed fromunderneath and from thecontact spring side of'the carrier, or as seenfrom the top side of the sponding to 0, 01.12, c, a#, b, and 0 of the fdrawing and from beneath. Thus viewed the order of the contacts is thereverse oi that shown in Fig. 1, so that whereas in Fig. 1 the orderfrom left to right is g, k, in Fig. 5 it is k; g, from left to right. InFig. 5 the number of contact springs requisite to the octave,-as from ato c inclusive, are shown,

g, g g, g", g, and h respectively correscale.

In the drawing, D represents a battery ee A41 B47 A48, d B48, achrePresents a note sounding device of the usualelectro-magneticconstruction for the control of the speaking of anorganpipe associated therewith, said pipe not being shown: in the drawing.Each of the note sounding devices A, A", A, is designed to controlthespeakin of a-diflerent organ pipe of a reg- 'ister, w ile the notesounding devices B, Bf', B, are each designed to control the speaking ofa difierent organ pipe of another three note sounding devicescontrolling the organ pipes of a register, while B, B, B, represent thecorresponding note sounding devices controlling the organ pipes ofanother register. A, A, and A, as representing notesounding devicescontrolling organ pipes serially an octave apart. And so with regard tothe note sounding devices 13, B and B.

A tO-A inclusive and B to B inclu- It is desirable to consider register.A, A, A may represent any si-ve represent carriers of insulatingmaterial I a each independently movable longitudinally and each designedto carry contacts represented by g, h, and 2'.

A, A, A, and B, B, 13, represent switchbars of conducting material.Switchbars A A, and A, are placed adjacent to and at right angles to thecontact carriers A to A inclusive. and B are placed adjacent to and atright angles to carriers B to B inclusive. Switchbar A is placedadjacent to the 9 contacts of carriers A to A inclusive.

Switch-bar B is placed adjacent'to the k contacts ofcarriers- B to 18 inclusive. Switch-bar B is placed adjacent to the 2'contacts of carriers B to B inclusive.

Each switch-bar is movable in relation to the adjacent contacts. Therelation of each switch-bar to its adjacent contacts is such SwitchbarsB B that when a contact and itsadjacent switchbar are in the unoperatedposition they are out of engagement and can only be brought intoengagement upon their being conjointly in the operated position. It isthe function of the several carriers to bring their contacts into therange of movement of the switch-bars adjacent to those contacts.

For the purpose of facilitating the drawing of the claims and for thesake of simplitying the description of thisinvention eacli switch-barand its adj acentlcontacts are considered as constituting a multiplecircuit closer since by these instrumentalities any one of severalcircuits may be closed by the movement of the switch-bar and the propercarrier to their operative positions, each multiple circuit closertherefore including independently movable contacts and a switch riers Bbar, each contact and the adjacent switchbar constituting a completecircuit closer within the meaning of certain of the appended claims.Thus the g contacts of carriers A to A inclusive and the adjacentswitchbar A constitute multiple circuit closer No. 1: the h contacts c.carriers A to A inelusive and the adjacent switch-bar A con stitutemultiple circuit closer No. 2: the i contacts of carriers A to Ainclusive and the adjacent switch-bar A constitute multiple circuitcloser No. 3: the 9 contacts of carriers-B to B inclusive and theadjacent switch-bar B constitute multiple circuit closer No. 4: the hcontacts of carriers B to B inclusive and the adjacent swltch-bar Bconstitute multiple circuit closer No. 5:;

switch-bar A of multiple circuit closer No.

1 is moved to operativeposition. Similarly the operation of keys' A A BB B closes circuits-through electro-magnets A, A", 13 B B and moves theswitch-bars A, A B B, B of multiple circuit closers 2, 3, at, 5, 6, tooperative position.

It, now, while stop A is drawn switch-bar A be moved by depressingkey A a circuit is closed through the note sounding device B by reasonof the engagement of the contact'h of the operated carrier A by theoperated switch-bar A; if switch-bar A be moved by depressing key A acircuit is closed through the note sounding device 13 by reason of theengagement of the contact 2' of the operated carrier A by the operatedswitch-bar A.

If the stops and keys be operated 001-. lectively in any combination theabove described results are in no way changed.

What has above been described with reference to the operation of the Astops and A keys is equally applicable to the operation of the B stopsand B keys in which case the B carriers and B switchbars are involvedinstead of the A carriers and A switches.

The circuits involved can be readily traced by one skilled in the art.

If keys A A A", be considered as be-' longing to one keyboard and B B Bas belonging to another keyboard it follows that a given note soundingdevice can be operated by a key in either keyboard either of the samepitch, or of the octave below, or of the octave above, singly or simultaneously.

It is obvious that further duplications of keyboards requires but a likeduplication of the arrangement shown and described.

It is obvious that equivalent electromagnetic apparatus, as solenoids,may be substituted for the electromagnets.
